As sunlust said above, from an seo point of view they are on a par if you use their seo plug-ins / modules. But for ease of use it has to be Wordpress in particular for smaller sites. Joomla is pretty complicated in comparison with Wordpress, but is certainly more powerful and comes with a huge range of add on modules and support. I’ve found that with a simple site Wordpress will let you set the whole lot up, including theme edits, in a couple of hours, whereas Joomla takes a lot longer.
